... You dont seem to understand what I meant by something in common. You're claiming that neither Malwarebytes, Google Chrome, or windows had an update that went live?When you left your laptop at home, you're saying that your laptop did not encounter pending updates from any apps or for the OS? You can't possibly know that. I happen to know that only a few days ago Malwarebytes updated. There is a memory leak from that app somehow, and it has been caused today within the last 24 hours by all of us here. Obviously SOMETHING has been changed, and the likely cause is an update, either one that came recently, or one that has just gone live. Updates contain file patches and new code that often alter, add to, or remove processes, or sub-processes from apps, which in this case could have caused the app to malfunction, e.i. the memory leak.
